Claims

[Scope of utility model registration request]

A die and a punch that are attached to the press so that they can approach and separate from each other and work together to press-form a workpiece when they approach, and a die and a punch that are attached to the same side as the press and that precede the punch when they approach the die. a blank holder that cooperates with the die face of the die to clamp the workpiece, the press die for drawing forming having a part on the mold surface of the die that protrudes more toward the punch than the die face; is divided into a die main body and a split die including the die face, and the split die can be raised and lowered relative to the main body, and the split die is placed on standby at the same height as the die main body or at a height closer to the punch than the die main body. A press mold for drawing forming, characterized in that it is biased to do so.
